A randomized, controlled trial of video supplementation on the cataract surgery informed consent process.
Trial report in Graefe's archive for clinical and experimental ophthalmology = Albrecht von Graefes Archiv fur klinische und experimentelle Ophthalmologie, 2019. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT06528509 (An Artificial-intelligence-powered Intervention to Aid the Informed Consent Process for Cataract Surgery for English Speaking and Bengali Speaking Patient Population Groups), which is not on this map. Cited by 21 papers, 2 of them syntheses that pooled it.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.

Abstract
purposeTo assess the effects of the American Academy of Ophthalmology's 2015 patient education video on patient information retention and anxiety preoperatively, on the day of surgery and postoperatively.
methodsThis is a prospective, surgeon-blinded randomized controlled trial at the University of Chicago Medical Center. Ninety-one patients with a diagnosis of first-eye cataract were randomized into either a video or control group. Subjects in both groups received face-to-face discussion with the surgeon and an informational brochure at the preoperative evaluation. Participants in the video group then viewed a four-minute educational video at the preoperative evaluation and on the day of surgery. Both groups completed an information retention quiz and a state anxiety assessment at the preoperative visit, on the day of surgery, and on the postoperative week one visit. Subject understanding of cataract surgery was measured using a twelve-question multiple choice quiz. State anxiety was measured by State Trait Anxiety Inventory-Y1 survey score.
resultsParticipants in the video group did not score significantly higher on the information retention quiz compared with the control group at the preoperative evaluation (8.7 ± 2.4 vs 7.7 ± 2.5, P = 0.07), but did so on the day of surgery (11.2 ± 0.8 vs 8.4 ± 1.7, P < 0.001) and postoperative week 1 visit (10.8 ± 1.5 vs 9.0 ± 2.0, P < 0.001). Subjects in the video group were significantly less anxious on the day of surgery (26.4 ± 5.1 vs 41.1 ± 10.3, P < 0.001).
conclusionsVideo supplementation to the traditional informed consent process demonstrated an improvement in patient understanding of cataract surgery at multiple timepoints and decreased anxiety on the day of surgery.
